Processing cartridge

Abstract

Provided is a processing cartridge detachably installed in an imaging device. The processing cartridge includes a first unit and a second unit, and a movable assembly coupled to and receive force from the force applying portion. When the processing cartridge is assembled to the imaging device, the first t and second units can be switched between states of approaching and separating. The movable assembly comprises an installing part and an acting part movable relative to and connectable with each other. The movable assembly is installed in the processing cartridge by the installing part, the acting part is coupled to the force applying portion and receives force from the force applying portion, to force the first and second units to switch between the two states. The acting part is retractable relative to the installing part and comprises an acting block and a guide block guided by the installing part.

What is claimed is: 
     
       1. A processing cartridge detachably installed in an imaging device having a force applying portion, comprising a first unit and a second unit coupled to each other, and a movable assembly capable of being coupled to the force applying portion and receiving a force applied by the force applying portion;
 wherein when the processing cartridge is being assembled to the imaging device, the first unit and the second unit are capable of being switched between a state of approaching each other and a state of separating from each other, 
 wherein the movable assembly comprises an installing part and an acting part that are capable of moving relative to each other and connectable with each other, the movable assembly is installed in the processing cartridge by the installing part, the acting part is coupled to the force applying portion and configured to receive a force applied by the force applying portion, to force the first unit and the second unit to switch from the state of approaching each other to the state of separating from each other; 
 the acting part is retractable relative to the installing part; and 
 the acting part comprises an acting block, and a guide block guided by the installing part. 
 
     
     
       2. The processing cartridge according to  claim 1 , wherein the installing part is installed in the processing cartridge in a manner of being rotatable around an axis, and at least a part of the acting part is movable relative to the installing part. 
     
     
       3. The processing cartridge according to  claim 1 , wherein the installing part is installed in the processing cartridge in a manner of being rotatable around an axis, and a length of the movable assembly is variable in a movement direction of the acting part. 
     
     
       4. The processing cartridge according to  claim 1 , wherein the installing part is installed in the processing cartridge in a manner of being slidably guided by a guide member, and at least a part of the acting part is movable relative to the installing part. 
     
     
       5. The processing cartridge according to  claim 4 , further comprising an unlocking mechanism coupled to the movable assembly, wherein when the movable assembly is locked by a locking mechanism, at least a part of the movable assembly retracts back into the processing cartridge, and when the movable assembly is no longer locked by the locking mechanism, at least a part of the movable assembly protrudes out of the processing cartridge and receives a force from the force applying portion. 
     
     
       6. The processing cartridge according to  claim 5 , further comprising a power receiving member configured to receive power to drive a rotating member in the second unit to rotate, wherein the unlocking mechanism is coupled to the power receiving member, and as the power receiving member rotates, the unlocking mechanism unlocks the movable assembly. 
     
     
       7. The processing cartridge according to  claim 5 , wherein the unlocking mechanism is installed in a manner of being movable along a longitudinal direction of the processing cartridge. 
     
     
       8. The processing cartridge according to  claim 1 , wherein the processing cartridge further comprises an elastic member abutting against the acting part, and under an action of the elastic member, the acting part has a tendency to approach the installing part. 
     
     
       9. The processing cartridge according to  claim 1 , wherein a gap is formed between the acting part and a component forced by the acting part before the acting part receives a force applied by the force applying portion. 
     
     
       10. The processing cartridge according to  claim 1 , wherein an extending and retracting direction of the acting part is substantially parallel to a movement direction of the force applying portion. 
     
     
       11. The processing cartridge according to  claim 1 , wherein the movable assembly further comprise a restriction column provided on the installing part, and the restriction column is configured to abut against components except for the movable assembly. 
     
     
       12. The processing cartridge according to  claim 1 , wherein the installing part is installed in processing cartridge in a manner of being capable of moving along a straight line, the processing cartridge further comprises a rotating member rotatably installed therein, and when the acting part receives a force applied by the force applying portion, the first unit and the second unit are separated from each other by the acting part through forcing the rotating member in the second unit. 
     
     
       13. The processing cartridge according to  claim 1 , wherein the second unit is configured to accommodate toner, the first unit is configured to accommodate waste toner produced during a working process of the processing cartridge, and the installing part is installed in the first unit. 
     
     
       14. The processing cartridge according to  claim 1 , wherein the first unit is rotatably provided with a rotating member, and the installing part is installed on the rotating member. 
     
     
       15. The processing cartridge according to  claim 11 , wherein the rotating member comprises a photosensitive member for receiving toner, and the installing part is installed on the photosensitive member. 
     
     
       16. The processing cartridge according to  claim 1 , wherein when the processing cartridge is being installed to the imaging device, along a vertical direction of the processing cartridge, a free end of the movable assembly is not opposite to the force applying portion.
